Table 1 M40 single-board functions and features

Functions and Features	Description
Basic Functions	Realizes multiplexing up to 40 single-wavelength optical signals into one combined signal. M4001: multiplexes up to 40 even-wavelength optical signals into one combined signal. M4002: Multiplexes up to 40 odd-wavelength optical signals into one combined signal.
Online Optical Power Monitoring	Provides an online monitoring optical port from which a small amount of optical signals can be output to a spectrum analyzer or a spectrum analyzer board to monitor the spectrum and optical performance of the combined-wave optical signals without interrupting the service.
Alarm and Performance Monitoring	Provide optical power detection function and single-board alarm and performance event reporting function.
Optical Layer ASON	Support
